Detailed explanation-1: -Gene Transfer: The introduction of new DNA into an existing organism’s cell, usually by vectors such as plasmids and modified viruses. Cells may be modified ex vivo for subsequent administration to humans, or may be altered in vivo by gene therapy given directly to the subject.
Detailed explanation-2: -GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells.
